checkboxes

[Anon]

Hey!

I´ve got a formular with ten checkboxes. I want to check that all of then are "on" before you can change site with the "submit-button".

How skall I code/write?

Please HELP 🙂

give them names like checkbox[1], checkbox[2] etc. this will cause the script to receive an array. loop through that array (eg with for ()) and check the value to be true.

Actually, you can just use

if(count($checkbox)==10)
{
//all is good
}
else
{
//go back...not all 10 checked
}

If you name them as arrays, and they are not checked, then the array entry isn't even made. So the count will be less than 10.

If you want to check that all are checked prior to the submit, you may want to use JavaScript to check the form. Give the checkboxes an array name (name[1], name[2], etc.) and then create a function that is called onSubmit that loops through the array to check each element returns a valid value. Unfortunately, if the user doesn't have JavaScript enabled, it won't work. A combination of the two is best and offers the most efficiency, if JavaScript is enabled the form is validated client side saving time, if not, the form is validated server side as a back up.

Just curious, why would you require all checkboxes for a form to be checked when a checkbox constitutes a choice? Just wondering.

I can tell you what I did when I needed something you're talking about 🙂

here goes the html source code for checkboxes:
<input type="checkbox" name="fet" value="1">Fet
<input type="checkbox" name="tolt" value="1">Tolt
<input type="checkbox" name="trot" value="1">Trot
<input type="checkbox" name="gallop" value="1">Gallop
<input type="checkbox" name="pass" value="1">Pass

Here goes the validation code:
checkbox($fet, "Cfet", "Fet");
checkbox($tolt, "Ctolt", "Tolt");
checkbox($trot, "Ctrot", "Trot");
checkbox($gallop, "Cgallop", "Gallop");
checkbox($pass, "Cpass", "Pass");

And here goes the function for this:
function checkbox($a, $b, $c) {
if($a == "1") {
echo "<input type=\"checkbox\" name=\"$b\" value=\"1\" checked>$c\n";
} else {
echo "<input type=\"checkbox\" name=\"$b\" value=\"0\">$c\n";
}
}

Now, I don't know if you like this or not but I needed to do it this way 🙂

Hope it helps, Arni
